WALP, oE BEnwICmrENNsYLvANiA, AssrGNon To AMERICAN CAEAND EOUNDEY COMPANY, OF Yonai, N. Y., A CORPORATION or NEW JERSEY NOCE ` This `invention relates to roofs-and, more particularly, to roofs of the type having framing consisting principally oi' a 'plurality of small units'or members which are bolted 51 together to form a'lreticular frame structure;

anditis an object of this invention-to provide a roofjframe of theI type described, in f'which a plurality of units ofbut a single design and of uniform dimensions are used. 104 It' is also an object of this invention to provide a roof frame sofdesigned thatfthe units @may be y formed of pressedy metal and all unitsfor a roof may be formed Vwith a single setofdi'es. p l5,V ANVith these land Otherjobjccts in view, as will appearmore fully hereinaftenthe in# vention consists substantiallyfin the Yconstruction, combination, location and relativen `arrangement of the parts, all as will be more fully herein set forth, as shown in the accompanying `drawings andV finally pointed s outin the appended claims.

positioned Castings i Where itis necessary Q or desirable to relieve' the. Vwallety A'the ,thrust from .the rods" y6tie rods 8"eXtend between oppositely positioned castings 3 beneath the rods 6 andI are securedito flanges 10 .of the castings by bolts or pins 12. `Extending between adjacent rods 6 are the unitsfor mein-` bers 14, each unit comprising a press-ed metal member consisting of a web 15 with its .ends 16 andlSbent in opposite directions and formed with oppositely disposed recesses 20 and 22 which are of sufficient depth in the ends tofit the rods 6 and which extend into fthe body of the .unit forming reinforcing corrugations therefor and-merging intothe web 15`as they approach the center of the member. Along the longitudinal edges, the

units 14 are provided with outwardly dis` posed flanges 24 which tapertowards the .endand merge with the ends-of the units.

The units or members" 14 are placed as shown 1n Fig. 2 withthe ends of the units 14 on the same sidefof a rod abutting and disposed adjacent ends of other units on the.

opposite side of the same rod, which ends co operateto form a tube through which extends the rod 6. The ends outside the recesses 2() and 22 are provided withbolt openings 26,

- and bolts l28' which extend through these,

openings and through openings in bracket or tie plates "30 servetol unite thel endsvof the units to each other and to secure the units to the rods 6. Thot-ie yor bracket plates 30 are placed one on eachside of a` rod, lapping the adjacents of units 14, and arey formed with recesses whichreceive the. recessed portions 'of the ends land 18 of theunits andl with voutwardly projecting flanges 32 uponwhich rest the purlins 34. The purlins 34 are, se-V cured tothe flanges 32 bybolts 36 `which secure the Vfurring'strips 38 to the purlins 34 andl which pass through alined openings in the purlins 34 and flanges `32. At the ends of the rods 6 the endsof` but two of the units or members come together and at these pointsV .the bracket plates '30 are but half the length of the plates usedv where the ends of four of the units `or members come together. In this connection, it will be noted that the rods 6.

are bent, soas to form chords of equal length,

l Cilv the points or' bending coming at the point of junction'oil the ends or" the units. The ends of the units lll are cut so that the abutting edges bisect the angle formed by the sections of the rod 6; this. being done in order to provide a joint in which there will be no overlapping of the units on the same side of a rod 6'.

Where the purlins cross the rods 6, betwee the unit joints, supports for Vthe purlinsare providedY by Vmeans of pairsof the bracket plates which tit about the rod 6 and are secured thereto by bolts as at and have the purlins 34 attached to the ilanges as previously described. TWhere it is desired to place purlins which cross the units en members 14 at points other than at the joints of the units, the upper flanges of the units are provided -with bolt openings and the purlins 34 are secured to the flanges by bolts which engage in openings inutlie'purlins and in the openings 40.

In theerection of this roofframing, the units or members 14 will be attached to an end wall or. an end rod 6 and project diagonally outward therefrom to the adjacent rod 6. The units or members le between that rod andthe next rod will be attached to the units alreadypositioned Aand the rod` 6 extending between the adjacent ends. manner a plurality of substai'itially` diamondshaped ligures will be formed whichv will be attached to the rods .6 and will extend from end to end of the roof. To this the Ypurlins 34 and furring strips 38 will be secured and upon the furring strips will be nail-ed the roof boards 42.

While the preferred form 'of tlieinvention has been shown and described, it is to be understood that the invention is not limited to the exact details of` construction shown and described, as it isobvious that various modi tications thereof within the scope of the art. l
